Engaging launch control and flooring the throttle will bring the revs up reasonaby high, dump and wheelspin leaving 11's down the road like a badass.
If you put it down halfway it will engage a proper no spin launch? Yes in the e46 it was something like that, I wanted to do the proper launch rather than the show boat one, but kept on leaving 11's on the road. Tried a few times one day on a quiet road it didn't hurt the car.

rickware said: I tried it loads of times and it just does massive wheel spins. I've tried various combos of putting the accelarator down slowly and quickly but they all hold the revs to 3400 and then give you excessive wheelspin. I think all this talk of clutch wear is over hyped probably driven by BMW Warranty as mine is solid and I've been trying to wear it out so I can get a performance one fitted. Traction off, S6, accelerator to the floor and hold the smg gear forward if anyone is wondering Lets have the VIN, so we all know what car not to buy!

So 10/11 years since the SMG-II box came out, did ANYONE actually have an E46 M3 clutch warranty claim refused because 'the black box said you did more than 3/5/11/236 launch controls sir' or for that matter even see on a computer somewhere the amount of LCs they had done? .. Or was it the forums fable that was never actually true?

Or was it the forums fable that was never actually true? I have checked this with BMWUK. They checked my cars history when authorising the clutch replacement under warranty last year, thats how i know the car has only ever done one launch. The dealer was very knowledgable when telling me what you can and cannot get away with. Same thing with the GTR if im correct, except that a single launch will void your warranty (tell me if im wrong).

Only on the first few months of GT-R's built, nissan then changed the launch control software and this then meant the warranty wasn't voided when traction control was removed. Obviously if you launched it 20 times in first 1000 miles they then could claim it was excessive use but you get the gist.

Boogsie said: Do it at least once It's amazing how much faster the car is when launched. Also, not 500hp. Only enough to move the car without tyres slipping. It's the whole point of launch control, to not just dump all 500hp into the wheels, but to feed it in as fast as the car/road can take it. Interesting point.

Lost count of the amount of times I used it on my last E60 M5. Dozens and my first clucth was not replaced until 80,000 miles, might be 90,000 I cant remember back that far! trick is don;t use M mode. Make sure soft comfort suspensions settings are used so that the car can "bog down" a little when using the launch control. Works fine and does take off a lot quicker, only issue will be a slight bouncing of the limiter between 1st to 2nd change and a fair bit of fish tailing It's fun, use it as much as you liek, BUT not when the car or the clutch is hot!

I've not looked at it that closely, but I thought it had to be M mode ?

Why is there a lot of fish tailing when going straight ? Do you choose softer suspension settings because softer rear suspension aids traction :-) ?

The softer setting allows the car to sit lower at the back when you pull away, meaning more weight on the rear tyres.
